[Q] Lost root when updating Busybox

Hello All - hope you can help me.
Until a few days ago I was on JSS15Q, unlocked and rooted using the excellent Wugfresh NRT. I downloaded an update to BusyBox as I was prompted, and since then I've lost root.
BusyBox (now v9.3) has a message stating "There was a problem opening a shell with root access. This is either being caused by superuser/supersu or by a device that is inproperly rooted. Try removing superuser/supersu permissions, uninstaling this application, reinstalling this application, and then regranting superuser/supersu permissions for this application."
SuperSU (now v1.65) has the message "There is no SU binary installed, and SuperSU cannot install it. This is a problem!".
Since losing root I've done the JSS15R OTA without issue, and last night I tried re-rooting using NRT (latest version) , but the same error messages as above appear.
Is there something obvious (and fool-proof!) that I can do to fix this? Is there any detail I've omitted?
Epic thanks in advance - Digi

Boot into TWRP and install SuperSU 1.55 (the 1.65 install script is a placeholder that does nothing)

sfhub - thanks
Before I boot into TWRP, what will installing SuperSU 1.55 actually do, if I'm already on 1.65? Why has updating BusyBox caused this problem, or is that a coincidental thing?

If you post the install script for the busybox you installed I can probably tell you what went wrong, but without that, any number of things could have gone awry.
SuperSU 1.55 should be OK to install on top of 1.65. It usually makes a reasonable attempt at cleaning up past installs before installing itself.

OK - how do I go about getting the install script? - I'd really like to find out what happened and why (might help someone else too!)

It is in the apk for busybox.

sfhub - thanks for your help. Root has been restored!
I installed SuperSU 1.55 via TWRP - I still don't know what went wrong or why, but it's fixed now - cheers. Now, where's that thank you button...

Unusual issues with SuperSu app

So I just tried to root the phone with
CF-Auto-Root-t03g-t03gxx-gtn7100.tar
Odin
Now the SuperSu app says "Unfortunately SuperSu stopped"
As written in other forums,solution I tried to UPDATE it through Google Play Store, THERE IS NO UPDATE OPTION.
I tried to use the UPDATE-SuperSU-v1.43 and flash it. But that too does not work as it fails while signature check and thus does nothing.
I tried to get an apk of supersu and tried to install that. It gives error "Supersu not installed"
I am stuck. I don't have root access and SuperSu is not working and it's not even updating.
I don't know what else to do.

Cannot update super su binary

I occasionally get a message stating "cannot update supersu binary. This is a problem" (something to that nature). I usually fix this problem by going into philz recovery and fixing root or manually flashing an older version of supersu. However, every time I reboot the phone I get the same "cannot update supersu binary". I am wondering if this could be a recovery issue. Every time I reboot through recovery or just reboot I have to update binary again. Is there a setting on philz that I am unaware of? I recently downloaded twrp manager and cleared cache and dalvik through that and when the phone rebooted I had no binary update issues.
Another thing I was wondering is could this be a Knox problem? I actually tried ota update to 4.3 ( i was rooted in 4.1.2) and it failed. Some time after manually upgrading to 4.3 I received a android security upgrade request. I did not accept the ota update. Is there any way to check if I have knox on my phone? Thank you

One thing I noticed. I dl a previous version of super su in recovery. I will have root access and all my apps that require root will work but there is no super su app. Once I dl supersu from playstore I will not be able to use apps that require root after rebooting

From CHAINFIRE:
Did you see the red Android logo during rooting, but SuperSU does not appear? This may sometimes occur due to left-over files and settings, however, you can usually install SuperSU from Google Play at this stage and it'll just work.

SuperSU on CM13

Hey all. I just flash that ROM. Works really nice. But I can't find SuperSu installed. Also apps which needs root permission didn't worked. I just go do download SuperSu from market and the program shows me an error told me to reboot and try again. Can you please help me? Thanks in advance.

You ALREADY HAVE root with CM-SU. To enable it, just go to developer option and give root permissions to app. Some SuperSU's versions are incompatible afaik. CM-SU preinstalled is just fine.

SuperSU is an issue for itself. Installing 2.74 using TWRP on my G3 lead to boot problems because of a boot image patch that SuperSU installs. If I restore boot partition before rebooting, SuperSU doesn't install. Using Play Store version fails to install su binaries.
Conclusion: use CM own root. It works nicely, just lost FolderMount but, well, I prefer that instead of losing phone.

Have you try this method http://forum.xda-developers.com/lg-g2/general/bump-supersu-t3273251
CustomPatcherScript_Bump.zip + UPDATE-SuperSU-v2.65-20151226141550.zip
But it's also can cause reboot loop
Do backup before doing flash that script
That worked fine with my D855 32Gb + CM13
